An apparatus securable onto a machine for tooling stationary parts, which provides a lubrication/coolant delivery system externally mountable upon a tool holder, of the type having a rotatable die head with a plurality of dies for machining the stationary part. The apparatus comprising a first internal ring member engaged to the tool holder for allowing rotation of the ring as the holder rotates, the internal ring further defining an annular channel for receiving lubricant/coolant thereinto; a pair of outer rings, for defining an exterior stationary housing surrounding the internal ring and defining a means for sealing the annular channel containing lubricant/coolant therewithin; a plurality of nozzles in fluid communication with the annular channel of the inner ring, each of the nozzles protruding out of the face of the inner ring, and extending downward to a position in relation to the rotation of each of the dies mounted on the rotating tool head, for providing a continuous and uninterrupted source of lubricant/coolant between lubricant/coolant pumped into the annular channel of the inner ring, and flowing out of the nozzles directed at the plurality of contact points between the plurality of dies and the work piece being machined. There is further provided a means for sealingly maintaining the lubricant/coolant within the annular channel, and means for providing easy rotation of the inner ring in relation to the stationary outer rings.
